<p>The objective of the present invention is to provide a syringe which does not have a plunger, is small and has excellent portability, and is capable of discharging a drug solution and sucking a biological sample such as blood with simple operation. The syringe (10) comprises a tube (30) that is provided with a nozzle (31) which is capable of sucking and discharging a liquid (33) on a distal end and an opening (37) on a base end, and a gasket (34) that is inserted into the tube (30) and sucks and discharges the liquid (33). The syringe (10) further comprises a tube outer magnetic body (41) that slides along the tube (30) and a tube inner magnetic body (35) that is inserted inside the tube. At least one of the tube inner magnetic body (35) and the tube outer magnetic body (41) is a magnet, and due to magnetic attraction or repulsion generated between the magnetic bodies, the tube inner magnetic body (35) slides when the tube outer magnetic body (41) is slided so as to slide the gasket (34) by pulling or pressing the same.</p> |
